4 Trends and Observations Rigidity of traditional IT environments and organizational boundaries are a significant impediment to rapid development and deployment of applications and services Workload and application requirements are becoming more diverse, more dynamic, and less predictable driving the need for a more flexible and adaptable infrastructure Abstraction and virtualization allows the resource within the IT infrastructure to become programmable which enables advanced automation and optimization The value offered by decoupling a virtual infrastructure from hardware is being realized across all elements of the infrastructure including servers, storage and networks 4 Software Defined Environements

6 What are Software Defined Environments? Software Software manages resources and components of an IT infrastructure instead of a human administrator Software understands the unique workload requirements Defined Infrastructure becomes aware of the software that runs on it. Environments IT infrastructure in general that can distributed across data centers and clouds In a software defined data center the elements of the underlying infrastructure (networking, storage, CPU) are virtualized All resources are exposed as services with an API and well defined functionality 6 Software Defined Environements

8 The Business Needs Time to Impact The Line of Business (LoB) of an enterprise needs to bring a new offering or product as fast as possible to the market. Standardization Reduction of the number of variations of the same Definition of a standard and the ability to build it in factory manner Priority Policy Service Transparency Knowledge on the status of the IT systems Ability to introspect the IT systems Accelerate Test and Develop Enablement for experiment and test new services Cost reduction Efficiency in build-up and management of IT systems 8 Software Defined Environements

OpenStack is an industry standard approach to control layer programmability. It s a Cloud Operating System Open Daylight is an open source software project to build a Software-Defined Networking platform. Openflow is an open standard protocol that support SDN by enabling the capability to separate the high level routing decisions (control path) from the fast packet forwarding (data path) functions of a switch. 14 Software Defined Environements

17 Software Defined Network vmware NSX NSX Manager : The NSX Manager is the centralized network management component of NSX, and is installed as a virtual appliance on any ESX host in your vcenter Server environment. It provides an aggregated system view NSX v Switch : NSX vswitch is the software that operates in server hypervisors to form a software abstraction layer between servers and the physical network NSX Controller: NSX Edge: Source: vmware 17 Software Defined Environements NSX controller is the central control point for all logical switches within a network and maintains information of all virtual machines, hosts, logical switches, and VXLANs. NSX Edge provides network edge security and gateway services to isolate a virtualized network. You can install an NSX Edge either as a logical (distributed) router or as a services gateway.

18 Software Defined Network vmware NSX Physical View VMs in a Single Logical Switch Transport Subnet A /24 Transport Subnet B /24 VM1 VM2 VM Logical Switch 5001 vsphere Distributed Switch Physical Network The NSX logical switch creates logical broadcast domains or segments to which virtual machine can be logically wired. This allows for flexibility and speed of deployment while still providing all the characteristics of a physical network's broadcast domains (VLANs) without physical Layer 2 sprawl or spanning tree issues. A logical switch is distributed and can span arbitrarily large compute clusters. This allows for virtual machine mobility (vmotion) within the datacenter without limitations of the physical Layer 2 (VLAN)boundary. A logical switch is mapped to a unique VXLAN, which encapsulates the virtual machine traffic and carries it over the physical IP network. 18 Software Defined Environements Source: vmware

23 Overview Operating Model Processes People and Organization Operating Model Infrastructure & Technology Objective of an Operational Model is to achieve efficiency regarding the consumption of the given resources (People, Processes and Infrastructure) Objective of a Service Provider is to apply the best operation model for specific service in a given context Improvement in operating model significantly reduce efforts and costs in appropriate resource consumption (processes, people and infrastructure) Higher degree of automation in processes, infrastructure and applications do have a cost reduction impact in people and processes aligned costs 23 Software Defined Environements

24 Resource Dependencies Operational adjustments of one resource has impacts on the others Objective is to improve quality or reduce cost, or simply find the optimum of both KPIs Each operational adjustment requires a certain initial investment The operational adjustment itself should outperform the initial investment from a operational cost savings and quality improvement point of view + Work effort Improvement People & Organization Processes + People and Organization Process Efficiency + Processes Operating Model Processes + Process Efficiency Infrastructure & Technology Infrastructure & Technology + Grade of Automation The challenge is to find the resource adjustment with the highest benefit on quality and cost - driven by the lowest investment Work effort Improvement People & Organization Infrastructure & Technology + Grade of Automation 24 Software Defined Environements

25 SDE as Starting Point for Operational Transformation People are dependent on business processes Business processes are dependent on infrastructure, technology and IT processes People & Organization Business Processes Because of the complexity of the tool landscapes in enterprise data center, the right decision usually is to consolidate on Infrastructure and technology resources SDE Introduction of new or adapted business processes introduce a higher complexity when the Infrastructure and technology improvements has not been finalized first. Infrastructure Technology & IT processes 25 Software Defined Environements

26 Summary The significance of the Software Defined Environment concept cannot be underestimated. It represents a fundamental evolutionary shift that aligns with the way enterprises now make IT decisions today SDE as technology becomes more central to business strategy, new players are joining the conversation. Implications businesses are no longer thinking in terms of standalone IT products Today, the focus is increasingly on the outcomes that those investments enable. IT and the business side are coming closer together Software Defined Environment is precisely the strategy that can meet joint needs of IT and business The landscape changes so fast that no enterprise can afford to build systems for a single purpose, either from a time or a cost stand-point Responding to a new opportunity or competitive threat cannot wait for new hardware to be procured, installed and configured. It has to happen immediately. Software Defined Environment can enable that kind of rapid-response agility. It provides the means to enhance the business value of IT by removing the barriers that stand in the way of fast action. 26 Software Defined Environements
